The structure of plasma membrane makes it selectively permeable allowing it to regulate the passage of substances into and out of the cell.

Polar molecules and ion cannot easily across the hydrophobic portion of plasma membrane because it is hydrophilic. Polar molecules and ions usually across the plasma membrane with the help of transport proteins.
